  1. 1. Impact of different primary particles on Geant4 simulation execution time - study on protons and pions

    University essay from Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionen

    Author : Rebecca Jigström Madeira; [2021]
    Keywords : Geant4; Monte Carlo method; Large Hadron Collider; simulation time; collider experiment; Physics and Astronomy;

    Abstract : The High Luminosity Large Hadron Collider (HL-LHC) at CERN, an improvement to the LHC, scheduled to be operating in 2027, will further the potential for scientific breakthroughs in High Energy Physics. The project’s demand in computational resources, however, is predicted to exceed what will be available then. READ MORE

  2. 2. Coordinate conversion for the Hough transform

    University essay from Uppsala universitet/Högenergifysik

    Author : Edvin Eriksson; [2021]
    Keywords : particle accelerator; coordinate transformation; hough transform; uppsala; bachelor thesis; kandidatarbete; uppsala; fysik;

    Abstract : This thesis attempts to develop a conversion algorithm between local coordinates in constituent detector modules and global coordinates encompassing the whole detector structure in a generic detector. The thesis is a part of preparatory work for studying the Hough Transform as a means of track reconstruction in the level-1 hardware trigger in the upgraded trigger and data acquisition (TDAQ) system in the phase 2 upgrade of the ATLAS detector at CERN.

  3. 3. Using Graph Neural Networks for Track Classification and Time Determination of Primary Vertices in the ATLAS Experiment

    University essay from KTH/Matematisk statistik

    Author : Mattias Gullstrand; Stefan Maraš; [2020]
    Keywords : Time determination; graph neural network; graph attentional network; HGTD; vertex; node classification; particle physics; machine learning; Tidsbestämning; neurala grafnätverk; uppvaktande grafnätverk; HGTD; vertex; nodklassificering; partikelfysik; statistisk inlärning;

    Abstract : Starting in 2027, the high-luminosity Large Hadron Collider (HL-LHC) will begin operation and allow higher-precision measurements and searches for new physics processes between elementary particles. One central problem that arises in the ATLAS detector when reconstructing event information is to separate the rare and interesting hard scatter (HS) interactions from uninteresting pileup (PU) interactions in a spatially compact environment.

  4. 4. Discovery potential and characterisation of the parity properties of a new spin-0 boson at the LHC and HL-LHC.

    University essay from Uppsala universitet/Högenergifysik

    Author : AN Di; [2020]
    Keywords : hierachy problem; beyond Standard Model physics; LHC phenomenology; HL-LHC;

    Abstract : We investigated the discovery potential and possibilities of characterizing the parity of a new spin-0 boson at LHC and HL-LHC only using di-photon channel. Our results show that it is possible to have a 5σ discovery and characterize the parity at 2σ level for given combinations of couplings and masses. .. READ MORE
